Also, seriously, people, stop paying attention to Coulter. Her entire career is built off of pissing off people with fallacies and misinterpretations. She's a professional troll, and should be set to ignore like all of the good ones are.

Who would be? This is a person who makes a living saying inflammatory things to get attention. Now a bunch of people have given her attention for an inflammatory thing she said. Saying it again is about the most transparently predictable thing she could possibly have done.

She didn't call him a retard, she referred to him as the retard. Of course it's policy never to imply singularity in the event of a retard...always use the indefinite article a retard, never the retard.
